Answer:
Explanation:
Since momentum is a vector, you, indeed, in <em>two dimension</em> collisions, you can decompose it in two components, the x-direction and the y-direction, such as you do with the force, which is a vector too.
The law of conservation of <em>momentum</em> states that the total momentum before and after the collision are conserved.
Let's assume a collision in one dimension: x-direction.
If object A is moving to the right, its momentum is to the right. If objcet B is at rest its momentum is zero. Then, if when object A collides with object B, the first stops, the second must move to the right with a momentum in the x-direction equal to the momentum that object A initially had.
You can apply the same reasoning if object A is moving in two dimensions, and, a similar one, if object B is not at rest: at the end the momentum in each direction before the collision has to be equal to the momentum in each direction after the collision.

Answer:
The force constant of the spring is 735 N/m.
Explanation:
It is given that,
Mass of fruit, m = 1500 g = 1.5 kg
Compression in the scale, x = 0.02 m
We need to find the force constant of the spring on the scale. The force acting on the scale is given by using Hooke's law. So,
Also, F = mg
k is force constant
So, the force constant of the spring is 735 N/m.

time
s= 30m

6s
the average speed of the marble is 5s/m
As we know that friction force on box is given by
here we know that
here we have
m = 12 kg
so now we have
now we will have
so it required minimum 49 N(approx) force to move the block
